Lipstick Jungle star Kim Raver and her husband Manuel Boyer welcomed their second child, a son named Leo Kipling in New York City on Tuesday. Big brother Luke is 5.

The 24 veteran announced she was expecting in May and told OK! at the Mercedes-Benz Polo Challenge in August that pregnancy was flying by the second time around.

“It’s gone by so much faster because I’m busy with the first kid. You’re so preoccupied with getting your kid to school and bathing him that all of a sudden you think, ‘Oh, I’m in my third trimester.’ It’s amazing.”

Leo’s arrival will provide a new playmate for Brooke Shield’s daughter, Grier, 17 months. The two actresses co-star on Lipstick Jungle and go all the way back to grade school. Luke and Brooke’s firstborn, Rowan, 4, “get along so well.”

Lipstick Jungle premieres in January on NBC, but in the meantime, Kim, 38, can be seen in Vaseline lotion ads, for which she posed nude while pregnant, explaining, “I feel a lot more comfortable getting naked [while expecting] than I do when I’m not pregnant.”
